糠醛制备方法及用途

制备方法

1.由富含戊聚糖的农产品废料,如玉米芯、棉籽壳、稻糠和甜菜渣等用稀酸水解、脱水并蒸馏而得。 2.糠醛最初从砻糠中得到,农副产品中多含多缩戊糖经水解脱水即生成糠醛。许多农作物的茎,皮,仔壳都含有多缩戊糖,因此都能用作制造糠醛的原料。生产时,将玉米芯,棉子壳或甘蔗渣等原料用硫酸和水蒸气处理,然后经水蒸气蒸馏,分层,减压蒸馏,即可得纯度达99%的产品。糠醛的收离与原料,酸的种类和浓度及其他条件有关,通常与理论收率相差较大。工业上制造糠醛主要有两种方法。加压法适合大规模生产,将原料与稀硫酸在加压下蒸煮,用高压或过热蒸汽带出反应产物,经分馏后得糖醛成品;常压法是将原料与食盐等无机盐及及稀硫酸共煮并同时蒸出糠醛。 3.将100kg玉米芯粉碎成0.5～1cm2的小块,加入25kg 90%的硫酸和125kg食盐与水配成水解液,使水解液的体积为玉米芯的2.5倍。玉米芯与水解液搅匀后,加热至沸,即开始馏出糠醛的稀溶液,冷凝收集于分离器中。静置1～2h分出水相得粗糠醛。用水蒸气蒸馏法精制,得纯品。精制方法:糠醛放置时产生的酸性物质和树脂,可用水洗后减压蒸馏除去。也可用氯化钙、无水硫酸镁或无水硫酸钠干燥后再进行减压蒸馏。使用过的糠醛的回收方法是用水蒸气蒸馏后再分馏。其他的精制方法有在7%碳酸钠存在下蒸馏,馏出物加2%碳酸钠再蒸馏,最后在800Pa压力下减压分馏可得纯品。

用途简介

作溶剂，以及作为合成香料、糖醇、四氢呋喃的中间体。

用途

1.糠醛是制备多种药物和化工产品的原料，如2-呋喃甲酸、呋喃、四氢呋喃。由四氢呋喃可生产1，4-二氯丁烷，再被氰基取代后加氢得到1，6-己二胺，这是合成尼龙66的基本原料。还可以由糠醛生产呋喃西林、呋喃丙烯醛、呋喃丙烯酸、糠醇等，这些都是合成医药、农药、兽药、染料、香料等产品的重要原料。

2.用作萃取剂，从烃类混合物中萃取不饱和烃，从C4烃中萃取丁二烯，从脂肪烃与芳香烃的混合物中萃取芳香烃等效果良好。也用于润滑油、天然油脂、粗蒽等的精制，维生素A、D的浓缩，天然树脂的溶剂等。此外，糠醛还用于制备呋喃树脂、电绝缘材料、清漆、呋喃西林、顺丁烯二酸酐、四氢呋喃、糠醇等。

3.检定钴，测定硫酸盐。测定芳香族胺、丙酮、生物碱、植物油和胆醇的试剂。测定戊糖和多戊糖时做标准。合成树脂，精制有机物，硝化纤维溶剂，二氯乙烷萃取剂。

4.用作薄层色谱法测定氨基甲酸盐的显色剂。还用作戊糖和多戊糖测定用标准试剂。并用于有机合成及作溶剂。

5.用作溶剂，及作为合成香料、糠醇、四氢呋喃的中间体。^[27]

糠醛物化性质

外观与性状：: 无色至微红的-棕色油性液体带有杏仁气味
密度：: 1.145±0.06 g/cm3
熔点：: -38.7 °C
沸点：: 161.8±0.0 °C
闪点：: 58.3±0.0 °C
水溶解性：: Slightly Soluble (6.6 g/L)
折射率：: n20/D 1.527
蒸汽密度：: 2.23 Torr
存储条件/存储方法：: 库房通风低温干燥,与氧化剂、酸类、碱类、食品添加剂分开存放
稳定性相关：: 1.对金属无腐蚀性，可用铁、软钢、铜或铝制容器贮存。在空气中或遇光逐渐变为棕色，故应避光、充入惰性气体密封贮存。糠醛在氧气、空气、二氧化碳、氮气中放置40天后，生成氧化物(树脂状）的量分别为1.7%，0.3%，0.1%，0.05%。在糠醛中加入对羟基二苯胺、二苯胺、碘化镉、对苯二酚、连苯三酚或β-萘酚等，添加量0.1%即可有效地防止氧化。在糠醛中添加0.001%~0.1%的N-苯基取代脲、硫脲或萘胺，能够防止在60~170℃加热时生成树脂。
2.化学性质：糠醛具有醛的性质。例如与亚硫酸氢钠能生成加成化合物，氧化变成呋喃甲酸，还原得到糠醇。在浓氢氧化钾溶液中发生Cannizzaro反应，生成糠醇和呋喃甲酸。与氰化钾反应生成联糠醛（furoin）。与氨反应生成糠酰胺，与胺反应生成Schiff碱。将糠醛与钠石灰一起加热至350~400℃，或者用镍或氧化锌与铬，五氧化二钒作催化剂加热至200℃，转变成呋喃。精制的糠醛放置时，由于受到空气中氧的作用，发生分解、聚合等一系列复杂的反应，使颜色变深。加热或光照都能加速其分解、聚合反应。

2.对环境的影响:

一、健康危害

侵入途径：吸入、食入、经皮吸收。健康危害：蒸气有强烈的刺激性，并有麻醉作用。动物吸入、摄入或经皮肤吸收均可引起急性中毒，表现有呼吸道刺激、肺水肿、肝损害、中枢神经系统损害、呼吸中枢麻痹，以致死亡。

二、毒理学资料及环境行为

毒性：属中等毒类。急性毒性：LD5065mg/kg(大鼠经口)；LC50153ppm 4小时(大鼠吸入)；人经口500mg/kg最小致死剂量。亚急性和慢性毒性：狗吸入507mg/m3，6小时/天，5天/周，肝脂肪变性；人吸入7.4～52.7mg/m3×3个月，发生粘膜刺激、结膜炎、流泪、头痛。致突变性：微粒体致突变：鼠伤寒沙门氏菌7ul/皿。细胞遗传学分析：仓鼠卵巢2500umol/L。

危险特性：遇明火、高热或与氧化剂接触，有引起燃烧爆炸的危险。受高热分解放出有毒的气体。若遇高热，容器内压增大，有开裂和爆炸的危险。燃烧(分解)产物：一氧化碳、二氧化碳。

3.现场应急监测方法:

4.实验室监测方法:

空气中糖醛含量的测定：样品用活性炭或氧化铝吸附，再用气相色谱分析苯胺比色法《空气中有害物质的测定方法》(第二版)，杭士平主编盐酸苯胺比色法；气相色谱法《食品卫生理化检验标准手册》中国标准出版社

5.环境标准:

中国(TJ36-79)	车间空气中有害物质的最高容许浓度	10mg/m³
前苏联(1975)	居民区大气中最大允许浓度	0.05mg/m³(最大值；日均值)
前苏联(1975)	水体中有害物质最高允许浓度	1.0mg/L
	嗅觉阈浓度	1mg/m³

6.应急处理处置方法:

一、泄漏应急处理

迅速撤离泄漏污染区人员至安全区，并进行隔离，严格限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器，穿消防防护服。尽可能切断泄漏源，防止进入下水道、排洪沟等限制性空间。小量泄漏：用砂士干燥石灰或苏打灰混合。也可以用大量水冲洗，洗水稀释后放入废水系统。大量泄漏：构筑围堤或挖坑收容；喷雾状水冷却和稀释蒸气、保护现场人员、把泄漏物稀释成不燃物。用防爆泵转移至槽车或专用收集器内，回收或运至废物处理场所处置。

二、防护措施

呼吸系统防护：可能接触其蒸气时，应该佩戴过滤式防毒面具(半面罩)。眼睛防护：戴化学安全防护眼镜。身体防护：穿防静电工作服。手防护：戴防苯耐油手套。其它：工作现场严禁吸烟、进食和饮水。工作毕，沐浴更衣。保持良好的卫生习惯。

三、急救措施

皮肤接触：脱去被污染的衣着，用肥皂水和清水彻底冲洗皮肤。就医。眼睛接触：立即提起眼睑，用大量流动清水或生理盐水彻底冲洗至少15分钟。就医。吸入：迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难，给输氧。如呼吸停止，立即进行人工呼吸。就医。食入：饮足量温水，催吐，就医。

灭火方法：灭火剂：雾状水、泡沫、二氧化碳、干粉、砂土。用水灭火无效，但可用水保持火场中容器冷却。
